c#:Dataset读取XML文件动态生成菜单
Step 1:Form1 上添加一个ToolStripContainer控件
Step2:实现代码
private void Form2_Load(object sender, EventArgs e)
{
CMenuEx menu = new CMenuEx();
string sPath = "D:\\Menu.xml";//xml的内容
if (menu.FileExit())
{
menu.LoadAllMenu(sPath, toolStripContainer1);
}
else
{ MessageBox.Show("XML文件加载失败!"); }
}
/// <summary>
/// 菜单读取类
/// </summary>
public class CMenuEx
{
private string _Path;
/// <summary>
/// 设置XML配置文件路径
/// </summary>
public string Path
{
get { return _Path; }
set { _Path = value; }
}
/// <summary>
/// 判断文件是否存在
/// </summary>
/// <returns>文件是否存在</returns>
public bool FileExit()
{
if (File.Exists(_Path))
{ return true; }
else return false;
}
/// <summary>
/// 加载菜单
/// </summary>
/// <param name="menuStrip">母菜单对象</param>
public void LoadAllMenu(string sXmlPath, ToolStripContainer pToolStripContainer)
{
DataSet ds = new DataSet();
ds.ReadXml(sXmlPath, XmlReadMode.Auto);

insert into @TempTable
(UserID,UserName) values (2,'b')
select UserID,UserName
from @TempTable FOR XML PATH
运行这段脚本,将生成如下结果:
